3TODO: check wether stack-sharing is still effective 3TODO: better (earlier) error messages on broken transfer's
4TODO: more effective stack sharing by having one "default stack" for "simple" coroutines? 4TODO: destroy gets only called on cancel: fix(?)
5TODO: verify exception frame changes and force stack copies?

25 - minor documentation cleanup. 63.52
7 - add count accessor to Coro::Semaphore.
8 - add Coro::State::cctx_stacksize.
9 - just for the fun of it, do not rely on implicit context,
10 which can dramatically improve performance, but people
11 using windows-process-emulation perls do not care much about
12 performance.
13 - finally move socket-operations from Coro::Socket to Coro::Handle
14 to be able to unblock foreign sockets.
15
163.51 Sun Mar 4 14:18:04 CET 2007
17 - fixed a problem when you weakened references to Coro::State's
18 (patch by Yuval Kogman).
19
203.501 Wed Feb 28 12:44:07 CET 2007
21 - rename some global symbols as macosx from hell redefines
22 them without asking.
23
243.5 Tue Feb 13 20:22:53 CET 2007
25 - do AnyEvent model detection earlier, avoiding problems
26 caused by first using AnyEvent and later Coro::Event.
27 - implement and document Coro::Event event objects.
28 - fix a potential problem in Coro::Event causing crashes.
29 - initialise PL_comppad when creating a new coroutine,
30 avoids crashes on early coro destruction.
31
323.41 Mon Jan 22 19:19:49 CET 2007
33 - readline on Coro::Handle did not support undefined $/,
34 nor did it deliver partial lines on EOF or error.
35 - implement malloc fallback for stack allocation because
36 stupid broken idiotic OSX has a stupid broken
37 idiotic fits-the-whole-os mmap "implementation" and
38 my dick feels longer if Coro is portable even to
39 obsolete platforms.
40
413.4 Fri Jan 19 21:52:54 CET 2007
42 - remove t/09_timer.t, as it isn't really testing much
43 but was rather flaky in practise.
44 - async_pool coro would keep arguments and callback alive until
45 it was reused.
46 - cancellation of a coroutine could cause spurious idle calls
47 in cede_notself.
48
493.3 Sat Jan 6 03:45:00 CET 2007
50 - implement $coro->on_destroy.
51 - Coro::Event blocking semantics have been changed,
52 documented and - hopefully - improved.
53 - fix nice adding, not subtracting, from priority.
54 - fix ->prio and api_is_ready (patch by Mark Hinds).
55 - fixed an assert ("... == prev__cctx->idle_te")
56 that could errronously trigger.
57 - fix various large and small memleaks.
58 - use a (hopefully) more stable cancel implementation
59 that immediately frees the coroutine data.
60 - cede/cede_notself return a status now.
61 - added Coro::guard function.
62 - added a global coroutine pool for jobs (on my machine,
63 I can create and execute 48k simple coros/s with async,
64 and 128k coros with async_pool).
65 - Coro::AIO now uses the coroutine priority as io priority.
66
673.2 Fri Dec 22 05:07:09 CET 2006
68 - improve portability to slightly older perls.
69 - use cleaner coroutine destruction.
70 - simplify configuration for users.
71 - optionally (unrecommended) prefer perl functions over
72 their coro replacements.
73
743.11 Tue Dec 5 13:11:24 CET 2006
75 - fixed some bogus assert's, but as perl.h disables assert even
76 without NDEBUG (thank you very much), not too many people should
77 notice (that did include myself). Andreas König noticed, though :)
78 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
79 it. Also noticed by Andreas König :)
80 - save/restore tainted status.
81 - verified to pass the testsuite on my 5.9.5.
82
833.1 Mon Dec 4 23:03:40 CET 2006
84 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
85 - incompatible change: transfer flags are now per-state.
86 - give a better error message on deadlock.
87 - document Coro::nready.
88 - enhanced testsuite.
89
903.01 Sun Dec 3 23:47:42 CET 2006
91 - forgot to include Coro::Timer.
92
933.0 Sun Dec 3 22:57:25 CET 2006
94 - the "FINALLY COMPLETELY STABLE" release (coming soon:
95 the "FAMOUS LAST WORDS" release).
96 - implement a new stack sharing algorithm, which uses a stack
97 pool (size currently hardcoded).
98 - make stack sharing mandatory (it no longer uses a heuristic).
99 - eval/die no longer cause weird problems under heavy use.
100 - Coro::Event could cause livelocks if it was used but
101 no Coro::Event watchers were used.
102 - Coro::Event now uses asynccheck as prepare does not
103 check for changed watchers.
104 - Coro::Event allows multiple waiting coros and will wake up one
105 per event.
106 - Coro::Event should be cleaner and more efficient now.
107 - new utility function Coro::unblock_sub.
108 - document the sad fact that Event is no longer reentrant.
109 - putting a coroutine into the ready queue twice could under
110 some circumstances lead to stack corruption.
111 - minor incompatibility: subclassing Coro::State is supported
112 directly now without going through a _coro_state member.
113 - state/coro switching is much faster now.
26 - verys minor optimisations and cleanups. 114 - very minor optimisations and code/documentation cleanup.
115 - avoid problems due to compiler inlining.
116 - removed timers from Coro::Timer -> use AnyEvent instead.
117 - replaced Coro::idle coroutine by (cleaner) idle handler.
118 - updated to newest libcoro.
119 - implement enhanced support for valgrind.
120 - implement is_ready and return value for ready.
121 - removed Coro::Cont, it was a misnomer (it's generators),
122 and it was somewhat annoying to get it right. Will come back
123 if somebody asks for it :)
124 - many ->wait methods and Coro::Event could return
125 spuriously without the event having happened.

282.5 Tue Nov 7 12:22:33 CET 2006 1272.5 Tue Nov 7 12:22:33 CET 2006
29 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket 128 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
30 use AnyEvent, moved them to Coro/. 129 use AnyEvent, moved them to Coro/.
31 - added Coro::LWP which contains all the uglyness required to 130 - added Coro::LWP which contains all the uglyness required to
